带列表的用户控件 <myclass> 无法识别myclass中的公共财产

Question

I am attempting to do this: Post I Have Tried Over and Over But Failed 我正在尝试执行此操作：我反复尝试但失败的帖子

But even after following the examples and the accepted answer I can't get my page to recognise the properties of the class in the List<>. 但是，即使按照示例和可接受的答案进行操作，我也无法使我的页面识别List <>中类的属性。

This is the code behind my UserControl: 这是我的UserControl背后的代码：

namespace TEST.ctrl.forms
{
    public class listItem
    {
        public string Name { get; set; }
    }

    public partial class ddl : System.Web.UI.UserControl
    {
        [PersistenceMode(PersistenceMode.InnerProperty)]
        public List<listItem> ddlItem { get; set; }
    }
}

And this is the aspx page: 这是aspx页面：

 <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="frm_Test.aspx.cs" Inherits="TEST.forms.products.frm_Test" %> <%@ Register Src="~/ctrl/forms/ddl.ascx" TagPrefix="d" TagName="ddl" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>TEST</title> </head> <body> <form id="form1" runat="server"> <div> <d:ddl ID="ddl1" runat="server"> <ddlItem Name="Bob"></ddlItem> <ddlItem Name="Dave"></ddlItem> <ddlItem Name="Frank"></ddlItem> </d:ddl> </div> </form> </body> </html>

The page understands d:ddl and offers ddlItem as a property but doesn't know what ' Name ' is. 该页面理解d：ddl并提供ddlItem作为属性，但不知道“ Name ”是什么。 Am I missing something? 我想念什么吗？

ddlItem is a List so itself doesn't have a Name property. ddlItem是一个List因此它本身没有Name属性。 Your markup should look something like this: 您的标记应如下所示：

<d:ddl ID="ddl1" runat="server">
    <ddlItem>
        <asp:listItem Name="Alice" />
        <asp:listItem Name="Bob" />
    </ddlItem>
</d:ddl>

I'm not 100% sure you need the asp: prefix. 我不确定100％是否需要asp:前缀。 You may need to register the listItem class with another <%@ Register... drective. 您可能需要向另一个<%@ Register... drective注册listItem类。
